Is different edition of textbook under different ISBN?

is different edition of textbook under different ISBN?


i look up my college's bookstore , the textbook i need for english is focus on writing :paragraphs and essays . by kirszner. n the edition is 2nd 08.


the ISBN 13-9780312434236


publisher :Bedford / St. Martin's





i find the exact same info at amazon.com n half.com ,but none of them mention the edition .i search it on publisher's website ,but only the first edition is showing . and it's all under the same ISBN.


Is the first edition what i'm looking for ? because i couldn't even find it on the publisher's website and first edition is also out in 08.





what should i do ? this textbk cost so much in my college bookstore.


should i wait until the school stat n ask the instructor about it or buy it on amazon now ?





also , if a textbk's ISBN ,edition n title are all exactly same as the book in bookstore , but only the publish date is different , is that a right book ? i couldn't find the publish date on the textbook , but on the online college bookstore , it said the publish date is 07 . n on amazon n all other place it said 06.





thank you so much !!|||Actually, each textbook is supposed to have its own ISBN! Two different editions means two different ISBN.





I'm not sure about the publish date, but the two books should be exactly the same since they have the same ISBN :). It's my first time to answer a question in Yahoo Answers :), Hope my answer will help, Peace.
